Success Stories: NIW Approved for Computer Science & Machine Learning Researcher Advancing High-Accuracy Algorithms and Efficient Decision Systems

Client’s Testimonial:

“Thank you! It’s been a pleasure to work with you, too!”

On August 20^th, 2025, we received another EB-2 NIW (National Interest Waiver) approval for a Postdoctoral Scholar in the field of Computer Science (Approval Notice).

General Field: Computer Science

Position at the Time of Case Filing: Postdoctoral Scholar

Country of Origin: China

State of Residence at the Time of Filing: California

Approval Notice Date: August 20^th, 2025

Processing Time: 1 year, 7 months, 9 days

Case Summary:

North America Immigration Law Group (NAILG) framed this NIW around a proposed endeavor to develop machine learning methods and mathematical models with high accuracy and performance to enhance decision-making and optimize system efficiency work aligned with U.S. priorities in critical and emerging technologies such as AI. The record ties these contributions to use cases in finance, healthcare, and national security.

Research Focus and Contributions

The petition highlighted three integrated lines of work, which are optimal-sample strategies for multi-armed bandit problems that reduce experimentation while preserving accuracy, theory-advancing generalization guarantees for machine learning algorithms via stability analysis, and machine learning mechanisms that incentivize fair data sharing across heterogeneous user groups to build better models with fewer resources. Together, these advances deliver principled algorithms and frameworks that translate to more reliable, efficient AI systems.

Research Impact and Metrics

Peer-Reviewed Publications: 18 (17 peer-reviewed conference papers + 1 journal article), plus 1 preprint.
Citations: 440 independent citations.
Peer-Review Service: At least 66 completed reviews for selective journals and conferences.
Field Standing (selected): At least 8 papers rank among the top-percentile articles in Computer Science for their publication years.

Here is an anonymized excerpt from a recommendation letter that underscores the practical impact of his work:

“[Client] has advanced multi-armed bandit methodology, especially the pure-exploration setting by identifying gaps in prior theory and devising efficient algorithms that determine the needed number of trials and allocate resources with significantly lower computational cost. The techniques have informed practical algorithms published at premier venues in machine learning. Recognized expertise is further evidenced by reviewer service for top conferences (e.g., ICML, NeurIPS, AISTATS, STOC). Collectively, these contributions expand data-driven decision-making across sectors, enabling more accurate, low-cost choices in complex resource-allocation problems.”

Demonstrating Substantial Merit & National Importance

We demonstrated substantial merit by showing that the client’s algorithms improve accuracy, efficiency, and trust in AI systems. National importance was established through evidence that AI is a federally recognized critical technology area and a driver of economic growth and defense readiness; the petition connected these priorities to the client’s concrete results and adoption by independent research teams.

Well Positioned to Advance the Proposed Endeavor

With a Ph.D. in computer science, a sustained record of peer-reviewed publications in top venues, dozens of invited reviews, and an active U.S. research appointment, the client is well-positioned to continue advancing high-impact work in machine learning theory and applications. The record also documents a clear plan to extend these methods through ongoing collaborations and dissemination in leading conferences and journals.

NIW Approval and Outcome

Approved in 1 year, 7 months, and 9 days, this NIW recognizes a research agenda that strengthens U.S. leadership in AI by delivering rigorous, resource-efficient learning frameworks with broad applicability across critical sectors. NAILG is proud to have guided this petition and looks forward to the client’s continued contributions to decision-intelligent, efficient machine learning systems.

North America Immigration Law Group (Chen Immigration Law Associates) is a U.S. immigration law firm dedicated to representing corporations, research institutions, and individuals from all 50 U.S. states regarding I-140 immigration petitions. We specialize in employment-based immigration petition and have a proven record of high success rate for the categories of: EB2-NIW (National Interest Waiver), EB1-A (Alien of Extraordinary Ability), EB1-B (Outstanding Researcher/Professor) and O-1 (Alien of Extraordinary Ability).

Our Ten Thousand I-140 Approvals Provide Unprecedented Insight into the USCIS Adjudication Trend

With more than 58,000 EB-1A, EB-1B, EB-2 NIW and O-1 cases approved, we have first hand information on the manner in which the USCIS adjudicate I-140 cases. As the USCIS has constantly changed its adjudication standards for the EB-1A, EB-1B and EB-2 NIW categories, our firm's huge database of successful cases gives you unprecedented insight to USCIS adjudication trends. We carefully analyze the data for all of our cases and apply the results of our analyses toward giving our clients up-to-date advice and adapting our strategies such that we remain on par with the ever-shifting landscape of immigration law in the U.S. With us, you will always have access to important updates, strategies, and information so that you can make the most informed decisions about your case.

We Have Helped Hundreds and Thousands of Clients with Credentials and Backgrounds Similar to Yours

With our exceedingly large number of successful petitions, no matter what credentials you have, no matter your background and field of expertise, no matter your visa status or nationality, chances are we have helped hundreds or even thousands of clients just like you. Our clients are usually impressed with how well we understand their research and work. Our insight and understanding stems from the fact that we have handled many cases with elements similar to yours already, and this helps us devise the best strategies for each individual petition.

Vast Majority of Clients Came to Us Because of Referrals
